DESCRIPTION

Similar products on the market are generally divided into velocity type and flow type. The product is a velocity type, using a heater and two thermopiles for measurement. It is suitable for measuring air/gas velocity in open environments. Flow-type products are primarily used to measure the flow of liquid or gas through a pipeline, typically expressed in volume or mass.

Measurement Output

The product offers two output modes:

  1. Air Velocity Output Mode: Directly converts the A/D value to the air velocity value for output, which is very convenient!
  2. Raw Value Output Mode: Simultaneously outputs both the A/D value and the air velocity value.

The product continuously senses after being powered on and only outputs data upon receiving a command.
⬥ Refer to the "Output Curve" section on page 6 of the datasheet for more details.
